Description

Technical Field

[0001] This utility model relates to the field of nuclear power plant pipeline technology, specifically a support structure for a transport pipeline. Background Technology

[0002] Piping supports play a crucial role in the safe and stable operation of nuclear power plants. In the complex and unique environment of a nuclear power plant, numerous piping systems undertake the important task of transporting various media such as coolants and steam. The function of piping supports is to provide a stable supporting structure for these pipelines, ensuring that they maintain the correct position and shape during operation, and bearing the weight of the pipelines themselves, the pressure of the internal media, and the stress caused by thermal expansion and contraction due to temperature changes.

[0003] Currently, some existing pipeline support devices often use only simple clamps or single pressure plates to fix the pipeline. This method of fixing is prone to pipeline loosening and displacement when the pipeline is subjected to external impact or long-term vibration, leading to pipeline damage. In view of this, we propose a new pipeline support structure. Utility Model Content

[0004] The main objective of this invention is to provide a support structure for a conveying pipeline that can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention proposes a conveying pipeline support structure, including a support column, a groove formed on the support column, a right-angled support plate fixedly connected to the inner wall of the groove, a placement structure on the top of the right-angled support plate, and a buffer structure provided on the placement structure. The placement structure includes:

[0006] A placement arm is fixedly connected to the top of the supporting right-angle plate, and a dark chamber is provided on the placement arm;

[0007] A laser sensor transmitter is fixedly connected to one end of the darkroom, and a laser sensor receiver is fixedly connected to the other end of the darkroom.

[0008] A light-blocking plate is slidably connected to the inner wall of the placement arm, and a sliding plate is fixedly connected to the top of the light-blocking plate;

[0009] A connector rod is inserted into the inner wall of the sliding plate, and a placement seat is slidably connected above the placement arm.

[0010] Preferably, the buffer structure includes a fixed plate, an auxiliary plate is detachably connected to the outer wall of the placement arm, a slide rod is fixedly connected to the outer wall of the fixed plate, the inner wall of the placement seat is slidably connected to the outer wall of the slide rod, and a force-bearing plate is slidably connected to the outer wall of the slide rod. Four sets of force-bearing plates are provided, distributed in pairs on both sides of the placement seat.

[0011] Preferably, a fixing frame is fixedly connected to the top of the placement seat, a threaded rod is threadedly connected to the inner wall of the fixing frame, a curved pressure plate is rotatably connected to the outer wall of the threaded rod, and an adjusting disc is fixedly connected to the end of the threaded rod away from the curved pressure plate. The threaded rod is rotated by rotating the adjusting disc.

[0012] Preferably, the outer wall of the curved pressure plate is fixedly connected to a guide rod, and the outer wall of the guide rod is slidably connected to the inner wall of the fixed frame. Two sets of guide rods are provided on one set of curved pressure plates.

[0013] Preferably, the curved pressure plate is provided with a positioning groove, the pipe body is detachably connected to the curved pressure plate, and a positioning ring is fixedly connected to the outer wall of the pipe body.

[0014] Preferably, the top of the placement arm is provided with a water inlet groove, the outer wall of the placement arm is detachably connected with a cover plate, two sets of water inlet grooves are provided, and the arc-shaped bottom of the sliding plate will partially cover the water inlet groove.

[0015] This utility model provides a support structure for a conveying pipeline. It has the following beneficial effects:

[0016] (1) The pipeline support structure fixes the pipeline body by inserting the positioning ring of the pipeline body into the positioning groove of the curved pressure plate, and then rotating the adjustment plate to drive the threaded rod to move the curved pressure plate. The pipeline body is fixed by two sets of curved pressure plates. The two sets of curved pressure plates can be fixed by screws, washers and nuts through the through holes, achieving double fixing. This effectively avoids the pipeline body from shifting after fixing, ensuring the stable installation and fixing of the pipeline.

[0017] (2) Under normal circumstances, the reflective coating on the light-blocking plate of the pipeline support structure can block the propagation of laser. When the pipeline body shakes and the placement seat moves, if the displacement is small, the light-blocking plate can still block the propagation of laser and the placement seat can be reset with the cooperation of compression spring one, compression spring two, fixed plate, force plate and auxiliary plate. When the displacement is large, the placement seat drives the plug-in rod to move the sliding plate and the light-blocking plate synchronously, so that the laser irradiates the area without reflective coating. After the laser sensor receiver receives the laser signal emitted by the laser sensor transmitter, it issues an alarm signal, which facilitates timely dispatch of personnel for maintenance and ensures the safety and stability of pipeline operation.

[0025] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1 - Figure 5This utility model proposes a support structure for a conveying pipeline, including a support column 1, a groove 2 on the support column 1, a right-angled support plate 3 fixedly connected to the inner wall of the groove 2, and a reinforcing rib on the right-angled support plate 3 to improve the support effect of the right-angled support plate 3. A placement structure 4 is provided on the top of the right-angled support plate 3, and a buffer structure 5 is provided on the placement structure 4. The placement structure 4 includes a placement arm 41, and the placement arm 41 is fixedly connected to the top of the right-angled support plate 3. A dark chamber 42 is provided on the placement arm 41. A laser sensor transmitter 43 is fixedly connected to one end of the dark chamber 42, and a laser sensor receiver 44 is fixedly connected to the other end of the dark chamber 42.

[0028] In this utility model, a light-blocking plate 45 is slidably connected to the inner wall of the placement arm 41. The light-blocking plate 45 is a transparent plastic plate, and the outer wall of the light-blocking plate 45 is coated with a reflective coating. The coating made of metals such as aluminum and silver has a high reflectivity and can reflect the laser back, thereby achieving the purpose of blocking the laser propagation. The light-blocking plate 45 is not completely coated with a reflective coating. There are uncoated areas on both ends of the light-blocking plate 45, where the laser can pass through. A sliding plate 46 is fixedly connected to the top of the light-blocking plate 45. The top of the sliding plate 46 has an arc-shaped design. A connecting rod 47 is inserted into the inner wall of the sliding plate 46. A placement seat 48 is slidably connected above the placement arm 41. The outer wall of the connecting rod 47 is partially threaded. A threaded hole is opened at the bottom of the placement seat 48, and the connecting rod 47 is threaded into the threaded hole.

[0029] Furthermore, the buffer structure 5 includes a fixed plate 51, an auxiliary plate 52 detachably connected to the outer wall of the placement arm 41, a slide rod 53 fixedly connected to the outer wall of the fixed plate 51, the inner wall of the placement seat 48 slidably connected to the outer wall of the slide rod 53, and a force-bearing plate 54 slidably connected to the outer wall of the slide rod 53. Four sets of force-bearing plates 54 are provided, distributed in pairs on both sides of the placement seat 48. Two sets of force-bearing plates 54 are elastically connected to the fixed plate 51 through a compression spring 1, and the other two sets of force-bearing plates 54 are elastically connected to the auxiliary plate 52 through a compression spring 2. Under normal conditions, through the cooperation of the fixed plate 51, the auxiliary plate 52, the force-bearing plates 54, the compression spring 1, and the compression spring 2, the placement seat 48 is positioned in the middle area of ​​the placement arm 41, at which time the laser irradiates the middle area of ​​the light-blocking plate 45.

[0030] Furthermore, a fixed frame 6 is fixedly connected to the top of the placement seat 48. A threaded rod 7 is threadedly connected to the inner wall of the fixed frame 6. A curved pressure plate 8 is rotatably connected to the outer wall of the threaded rod 7. An adjusting disc is fixedly connected to the end of the threaded rod 7 away from the curved pressure plate 8. Rotating the adjusting disc drives the threaded rod 7 to rotate, thereby driving the curved pressure plate 8 to move. There are two sets of fixed frames 6, threaded rods 7, and curved pressure plates 8. A guide rod 9 is fixedly connected to the outer wall of the curved pressure plate 8. The outer wall of the guide rod 9 is slidably connected to the inner wall of the fixed frame 6. Two sets of guide rods 9 are set on one set of curved pressure plates 8. The movement of the curved pressure plate 8 is guided by the guide rods 9. Through holes are opened at both ends of the curved pressure plate 8. The two sets of curved pressure plates 8 can be fixed by screws, washers, and nuts through the through holes.

[0031] Furthermore, a positioning groove is provided on the curved pressure plate 8, and a pipe body 10 is detachably connected to the curved pressure plate 8. A positioning ring 11 is fixedly connected to the outer wall of the pipe body 10. The positioning ring 11 can be snapped into the positioning groove. By snapping the positioning ring 11 into the positioning groove, and then fixing the pipe body 10 by the curved pressure plate 8, it is possible to prevent the pipe body 10 from shifting after fixing. A water inlet trough 12 is provided at the top of the placement arm 41, and a cover plate 13 is detachably connected to the outer wall of the placement arm 41. Two sets of water inlet troughs 12 are provided. The arc-shaped bottom of the sliding plate 46 will partially block the water inlet trough 12, so that the liquid on the sliding plate 46 is guided into the water inlet trough 12. The water inlet trough 12 facilitates the drainage of water from the top of the placement arm 41. The cover plate 13 is used to seal the dark chamber 42.

[0032] In use, the positioning ring 11 is first inserted into the positioning groove, and the threaded rod 7 is rotated by rotating the adjustment plate, which in turn moves the curved pressure plate 8. The two sets of curved pressure plates 8 fix the pipe body 10, which can prevent the pipe body 10 from shifting after fixing. The through hole makes it easy to fix the two sets of curved pressure plates 8 with screws, washers and nuts. The double fixation ensures the fixing effect of the pipe body 10.

[0033] Meanwhile, under normal circumstances, the reflective coating on the light-blocking plate 45 will block the laser propagation. When the pipe body 10 shakes significantly, the placement seat 48 will be displaced on the slide rod 53. When the displacement is small, the reflective coating on the light-blocking plate 45 will block the laser propagation. Through the cooperation of the fixing plate 51, the force plate 54, the auxiliary plate 52, the compression spring one, and the compression spring two, the placement seat 48 can be reset after displacement.

[0034] When the displacement is large, the large displacement of the placement base 48 will drive the plug rod 47 to move synchronously. The plug rod 47 will cause the sliding plate 46 to slide, which in turn will cause the light blocking plate 45 to move synchronously. When the light blocking plate 45 undergoes a large displacement, the laser will irradiate the area of ​​the light blocking plate 45 without a reflective coating. At this time, the laser emitted by the laser sensor transmitter 43 will irradiate the laser sensor receiver 44. The laser sensor receiver 44 will receive the signal and generate an alarm signal, which will facilitate the dispatch of personnel for maintenance.

[0035] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
